BACKGROUND/PURPOSE: Bioabsorbable vascular scaffolds (BVS) are made from a radiolucent material. Their multiple implantations on a single long diffused segment requires a specific technique with imaging magnification, which could cause an increase in dose delivered during percutaneous coronary intervention (PCI) procedure. We aimed to identify differences in radiation dose, fluoroscopy and procedural times in Hybrid DES+ multiple BVS (Absorb, Abbott Inc., USA) implantation (hybrid metal/scaffold jacket) versus multiple III generation Drug-eluting stents (DES) (full-metal jacket) in patients with long and diffuse coronary artery disease of the left anterior descending (LAD) coronary artery...

BACKGROUND Development of a true coronary aneurysm after percutaneous coronary intervention is a rare event, and a coronary aneurysm resulting in acute myocardial infarction is even rarer. Coronary aneurysm formation after bioresorbable vascular scaffold (BVS) implantation, eventually leading to thrombosis, embolization, and myocardial infarction, has never been reported before in the literature. CASE REPORT A 62-year-old man received an elective BVS for a proximal left anterior descending lesion. Two months later, he suffered from a non-ST-segment myocardial infarction...

AIMS: The aim of this study was to investigate the impact of dual antiplatelet therapy (DAPT) termination on late and very late scaffold thrombosis (ScT) in patients treated with the Absorb bioresorbable vascular scaffold (BVS). METHODS AND RESULTS: Data from the registries of three centres were pooled (808 patients). To investigate the effect of DAPT termination on ScT after a minimum of six months, we selected a subgroup ("DAPT study cohort" with 685 patients) with known DAPT status >6 months and excluded the use of oral anticoagulants and early ScT...

BACKGROUND: Bioresorbable vascular scaffold (BVS) is a promising technology that potentially offers several advantages over contemporary coronary drug-eluting stents (DES). Crucial to BVS implantation is the correct choice of scaffold size (diameter and length) in order to avoid "geographic miss" in length, provide the maximal support to the vessel wall, and avoid leaving "free-floating" foreign material in the coronary vasculature. OBJECTIVES: To assess the optimal method for measuring coronary stenosis prior to BVS implantation...

BACKGROUND: Data regarding the long-term efficacy and safety of everolimus-eluting bioresorbable vascular scaffolds (BVS) compared with everolimus-eluting stents are limited. This meta-analysis aimed to compare the long-term outcomes with both devices. METHODS AND RESULTS: Randomized trials reporting clinical outcomes beyond 1 year and comparing BVS with everolimus-eluting stents were included. Summary estimates risk ratios (RRs) were constructed. The primary efficacy outcome was target lesion failure, defined as cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization, and the primary safety outcome was definite or probable stent/scaffold thrombosis...

INTRODUCTION AND OBJECTIVES: Bioresorbable vascular scaffolds (BVS) have the potential to restore vasomotion but the clinical implications are unknown. We sought to evaluate angina and ischemia in the long-term in patients treated with BVS and metallic drug-eluting stents (mDES). METHODS: Multicenter study including patients with 24 ± 6 months of uneventful follow-up, in which stress echocardiography was performed and functional status was assessed by the Seattle Angina Questionnaire (SAQ)...

Envelope fusion proteins (F proteins) are major constituents of budded viruses (BVs) of alpha- and betabaculoviruses (Baculoviridae) and are essential for the systemic infection of insect larvae and insect cell culture. An f homologue gene is absent in gammabaculoviruses. Here we characterized the putative F-homologue (Cuni-F), encoded by (ORF) 104 of Culex nigripalpus nucleopolyhedrovirus (CuniNPV), the only deltabaculovirus member. When expressed alone, this protein seems to locate on the cell surface and is able to induce cell-cell fusion...

Violence has a negative impact on adolescents and affects their quality of life. It causes stress and requires the victim's adaptive capacity, which can cause psychological and biological changes. Hormone cortisol levels have been used as stress biomarker in several studies. This paper aims to perform a systematic literature review of publications on cortisol and violence involving teenagers from 2000 to 2013. Descriptors "cortisol", "violence" and "adolescent" were used in both English and Portuguese in this review, which included bibliographic databases PubMed/Medline, Lilacs, BVS and SciELO...

The Absorb biovascular scaffold (BVS) is a bioresorbable, everolimus-eluting scaffold whose data on real-world patients with complex lesions are limited. Short-term follow-up from recent studies point to a higher rate of 30-day thrombosis than observed with drug-eluting stents. We aimed to understand the short-term safety and efficacy of BVS. Registro Absorb Italiano (RAI, ClinicalTrials.gov:NCT02298413) is an Italian, prospective, multicenter registry not funded, whose aim is to investigate BVS performance through a 5-year follow-up of all consecutive patients who have undergone successful implantation of ≥1 BVS in different clinical/lesion subsets...

Giant proteoliposomes are generally useful as artificial cell membranes in biochemical and biophysical studies, and various procedures for their preparation have been reported. We present here a novel preparation technique that involves the combination of i) cell-sized lipid vesicles (giant unilamellar vesicles, GUVs) that are generated using the droplet-transfer method, where lipid monolayer-coated water-in-oil microemulsion droplets interact with oil/water interfaces to form enclosed bilayer vesicles, and ii) budded viruses (BVs) of baculovirus (Autographa californica nucleopolyhedrovirus) that express recombinant transmembrane proteins on their envelopes...

Beneficial properties of bioresorbable vascular scaffolds (BVS) regarding to vasomotility restoration and no caging of the vessel make them attractive devices in chronic total occlusions (CTO) revascularization. However, more evidence is needed attending to their use in this specific setting. We aim to determine feasibility and safety of BVS use in CTO revascularization attending to struts coverage and apposition, as well as re-stenosis and stent thrombosis (ST) rates. 29 BVS were deployed in 9 CTO lesions revascularization (mean J-CTO score ≥3) with an acute procedural success rate of 100%...

Methods and Results: A systematic review and meta-analysis of randomized clinical trials comparing clinical outcomes of patients treated with BVS and EES with at least 24 months follow-up was performed. Adjusted random-effect model by the Knapp-Hartung method was used to compute odds ratios (OR) and 95% confidence intervals (CI)...

OBJECTIVES: The purpose of this study was to evaluate the economic impact of the Absorb bioresorbable vascular scaffold compared with the Xience everolimus-eluting stent in patients undergoing percutaneous coronary intervention. BACKGROUND: The ABSORB III trial (Everolimus-Eluting Bioresorbable Scaffolds for Coronary Artery Disease) demonstrated that the Absorb scaffold was noninferior to the Xience stent with respect to target lesion failure at 1 year. Whether health care costs differ between the Absorb scaffold and the Xience stent is unknown...

Bioresorbable vascular scaffold (BVS) stents have been proposed recently as an elegant technique for treatment of coronary artery disease. However, perspective that these "dissolvable" stents will replace conventional metallic stents in broad spectrum of clinical conditions and patient categories in the near future has been moderated by non-negligible incidence of stent thrombosis (ST). Mechanical factors, such as strut thickness and malapposition have been implicated in increased risk of BVS ST. Presently described is case of immediate partial BVS ST in a young male related to technical procedural problem, rather than mechanical problem...
